RS485 Wiring

For correct RS485 wiring: follow the RS485 wiring guidelines.
If the wiring shown in the table below is incorrect, please let us know.
There is no general industry consensus on the use of A and B for RS485 polarity, so the naming may be counterintuitive for some devices.

Device	SmartgridOne Controller model OM1	SmartgridOne Controller model IG8	RS485-USB converter	RS485-Ethernet converter
A	RS485 A	RS485_POS	RS485 A	TX+
B	RS485 B	RS485_NEG	RS485 B	TX-
N/A	RS GND	GND	Not available	G

Configuration

Ethernet

See the device manual.

RS485

NOTE: RS485 Device Addresses

You MUST give each device a unique address on the RS485 bus. Check the device manual for instructions.
Use lower addresses first (1, 2, ...) because the SmartgridOne Controller will find them faster!
For each device, it is generally recommended to keep the factory-default baud rate, parity, and stop bits. The SmartgridOne Controller will scan those first.
